BULKHEAD FOR SHIPS, 81,0.

SPECIFICATION forming part of Letters Patent No. 608,047, dated July 26,1898.

Application filed November 19, 1897. Serialll'o, 659,068. (No model.) i

To whom it may concern:

Be it known that I, MARJORY HUNTER, gentlewoman,a subject of the Queenof the United Kingdom of Great Britain and Ireland, residing at 11Goldenacre Terrace, Edinburgh, in the county of Mid-Lothian, Scotland,have invented an Improved Bulkhead for Separating Material in WVarehouses, Ships, or other Situations, of which thefollowing is aspecification.

This invention relates to an improved bulkhead for separating grain andother material in warehouses, ships, or other situations, and has forits object to provide a simple and efficient portable bulkhead which canbe readily erected and held firmly in position during use and which whennot in use can be readily taken down and stored into a small compass.

Figure l is an end view, and Fig. 2 a plan, showing a single bulkhead.Fig. 3 is an end View, and Fig. 4 a plan, of a double bulkhead. Figs. 5and 6 show modifications.

Referring to Figs. 1 and 2 of the said draw ings, I employ horizontalsleepers A, which are placed at suitable intervals on the floor of thespace to be occupied by the material being dealt with. On'the outer endof each of the sleepers A is a chock a, of hard wood, which may besecured to the sleeper by screws or other suitable means, and againstthe chocks a are placed vertical standards B, the

top ends of which are connected to the inside ends of the correspondingsleepers by tie-bars b, which are preferably made of steel and areprovided with hooked or bent ends Z), adapted to fit over the ends ofthe upright standards and the sleepers. The ties Z) are also preferablyformed with a twist, as shown, so as to increase their strength. Theboarding O, of suitable length, breadth, and thickness, is placedagainst the standards B and is retained in position by the pressure ofthe material being dealt with, the weight of which material alsoprovides fixity of base for the structure.

By the use of the tie-bars b it will be seen that no nails or screws areused in the erection of the bulkhead, so that it can be erected andtaken down withease.

Figs. 2 and 3 0f thedrawings illustrate a double bulkhead which isconstructed in a similar way to that first described, with the exceptionthat the sleepers A are made twice the length and are provided with twoupright standards B, the boarding 0 being placed be tween same. 7

I mayalso arrange the sleepers and provide chocks where necessary toenable two bulkheads to be placed at right angles to each other, or Imay arrange them so that asquare may be formed; also, instead ofsecuring a wooden chock upon the outer end of the sleeper by screws orother suitable means I may, as indicated in Fig. 5, make this chock aspart of an iron or other metal casting a, which is secured to the end ofthe sleeper by any convenient means, such as bya screw or screws orbolts 3. The said casting has an upper projection to form the chock forthe .foot of the vertical standards to bear against, and the sole 2 ofthe casting is made nearly flush with the bottom of the sleeper, exceptthat the said sole is roughened or cast with diamond or other shapedprojections for the purpose of causing the casting to grip into thefloor and so make the sleeper very firm. Without the said roughened solethe sleeper has to be a certain length in order to obtain the necessaryhold upon the floor, whereas by the use of my said roughened sole-piecethe length of the sleeper may be considerably reduced, thus reducing thecost, with greater efficiency.

As a modification the roughened sole-piece may, as shown in Fig. 6,simply be a cast-iron or other plate 4, let into the under side of thesleeper, the said plate being roughened in any convenient manner, so asto grip the floor, and secured tothe sleepers by screws or otherconvenient means.

A further improvement shown in Fig. 6 consists in providing a secondtie-bar 5 for the purpose of assisting in keeping the standards upright,this second tie-bar being a desideratum when an extra height of standardis employed. In this case I connect the one end of the second tie-bar 5,by suitable detachable fastenings, such as a hook andeye, to the centerof the length of the standards, the other end of the second tie-barbeing connected to the end ofthe sleeper or to another point in itslength.

It will be seen from the foregoing that quadrangular bins may thus beformed in ships holds for the purpose of keeping separate and distinctdifferent parcels of bulk goods-such as grain, salt, ore, &c. When a binis filled, it can be sheeted over and other large bulk put on top of andsurrounding the bin.

l. A portable bulkhead for separating grain and other material inWarehouses, consisting of horizontal sleepers, provided with chocks atone end, vertical stands resting on said horizontal sleepers and againstsaid chocks, tiebars having bent ends engaging over the ends of thesleepers and vertical standards, and
